My personal opinion is that they are slightly better cutting blades but accel in wet conditions better. Maybe its different with each grass culture but thats what I noticed with the bermuda grass we have here.

I use gator blades on my 36 wright and my 22" Push mowers. Most awesome blades on the market. at 14$ a pop they are pricey but, worth the extra money. I sharpen them about 1/2 as much as usual also so, cuts back on my labor.
